Anthony, Your killing me man! Without SIP ALG, I could not find any configuration to get 2 Polycom 335s Registered. NDLB-force-rport to "safe" - made no difference. I left rport to safe and tried removing : <variable name="sip-force-contact" value="NDLB-connectile-dysfunction"/> from this user. - WORKED!!! So on my FIOS router with SIP ALG on, Polycom and Cisco phones REQUIRE NDLB variable and LinkSys RPT300 CANNOT HAVE IT in the user profile. This is starting to feel a lot like witchcraft! Have you ever read about BF Skinner's pigeons that were given random reinforcement rewards? http://vidallena.org/skinpal.htm Thanks again, Sean From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Anthony Minessale Sent: Monday, December 17, 2012 8:55 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Linksys Registration disappears after 5 minutes Try going back to what you had that was working and instead of evil ALG etc: Set sofia profile param NDLB-force-rport to "safe" On Mon, Dec 17, 2012 at 7:44 PM, Sean Devoy <sdevoy@bizfocused.com> wrote: Hi, I have a Linksys ATA (RPT300). I have it successfully Registering through a NAT connection. But, 5 minutes later FS no longer shows it registered. The RTP300 still says it is registered and can of course dial out, but not in. For what it is worth, this RTP300 has been working for months and months. Since we now have Polycom phones on this LAN, we had to enable SIP ALG and NDLB. Cisco phones and Polycom phones are all working great now, but I cannot figure out what setting to change in the Linksys device. There are no words to express how much I hate NAT and SIP.
